Gearbox and Speed Reducers

Gearboxes and speed reducers convert motor speed into usable torque—quietly doing the heavy lifting behind conveyors, mixers, screw conveyors, aerators, and process drives. The right reducer means smoother operation, longer service life, and less energy wasted.

KSIS supplies worm gear reducers, shaft-mount reducers, inline helical and bevel-helical designs, screw conveyor drives, and C-face gearmotors—along with replacement parts and accessories. We can match ratios, mounting positions, and shaft configurations to drop into your existing installation.

Replacing an obsolete reducer? KSIS specializes in cross-referencing discontinued models to current equivalents, so you get a compatible unit without redesigning your drive.
